Based on the analysis of some air quality evaluation models and ecotourism's special requirements of air quality, the air quality index model of ecotourism areas was established. With the application of the new model, the recreational development effects on air quality in the Zhangjiajie National Forest Park in China's central province of Hunan were successfully evaluated, and the results showed that the recreational development affected the air quality of the park seriously. To improve the environmental quality of the park, measures must be taken to reduce the amount of waste gases, thus to realize the sustainable development of the park.
